Who won the 24 hours of Le Mans with a Gulf GR8 in 1975?

Derek Bell, a specialist of long races. A name linked with the Stuttgart automotive company Porsche. Often racing as a duet, with another champion Jacky Ickx, Bell climbed the Le Mans podium consecutively from 1981 to 1988, excluding 1984.
He won three times at the 24 Hours of Daytona, in 1986, 1987 and 1989, driving a Porsche 962.
He also raced nine F1 GPs, but with no interesting results. Officially, his career ended in 1993, with the Team Momo at the IMSA championship… but we often still see him on track!
